An artist's work should never be compromised by a sheet of paper that won’t last. For that reason, Winsor & Newton created Cotman Watercolor paper. Perfect for artists on a limited budget, this paper won't compromise your art or your wallet. It serves as an excellent alternative to 100% rag papers, primarily because it is mould-made. Its handsome cold pressed surface and 140 lb. weight make it ideal for most watercolor techniques. Cotman is an acid-free sheet, sized internally and externally. This allows for repeated reworking without damaging the surface. Each tape-bound block features 20 sheets of 140 lb watercolor paper, cold pressed and acidfree.
